(Spider dragline silk has a tensile strength of roughly 1.3 GPa. The tensile strength listed for steel might be slightly higher – e.g. 1.65 GPa, [24] [25] but spider silk is a much less dense material, so that a given weight of spider silk is five times as strong as the same weight of steel.)
In the last decade, much research has been done about spidroin protein and spider silk in order to take advantage of some of its properties, such as its elasticity and strength. Spider silk is used in different industries, and its range of applications in biomedicine is increasing every day.
The spider silk has a greater tensile strength than steel, and the material is even strong enough to stop a bullet. In terms of everyday usage, spider silk could be a huge game changer when it ...
The silk fibroins produced by insects and spiders are often classified as keratins, though it is unclear whether they are phylogenetically related to vertebrate keratins. Silk found in insect pupae , and in spider webs and egg casings, also has twisted β-pleated sheets incorporated into fibers wound into larger supermolecular aggregates.
The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. [4] Its silk is the toughest biological material ever studied. Its tensile strength is 1.6 GPa. [5] The species was named in honour of the naturalist Charles Darwin on November 24, 2009—precisely 150 years after the publication of The Origin of Species. [2]
The tensile strength for the three kinds of silk measured in the Blackledge study was about 1,000 MPa. The ultimate strength reported in a previous study for Trichonephila edulis was 1,290 ± 160 MPa. [22] The tensile strength of spider silk is comparable to that of steel wire of the same thickness.
